Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain Eurocopter France (Eurocopter) Model EC120B and EC130B4 helicopters. This proposed AD would require replacing parts of the sliding door star support attachment assembly, depending on the outcome of required inspections. This proposed AD is prompted by a report that passengers in a Eurocopter helicopter were forced to exit through the pilot door after landing because they could not open the sliding door from the inside. The proposed actions are intended to prevent failure of the sliding door star support attachment, which could inhibit operation of a sliding door from inside, delaying the evacuation of passengers during an emergency.
